Red Knot — size comparison — facts and sources
The red knot breeds in the High Arctic, often on dry, sparsely vegetated tundra slopes. During migration and winter it uses sea coasts, estuaries, lagoons and saltmarshes. Populations travel enormous distances, and suitable stopovers supply energy for later journey stages.
For much of the year it eats small bivalves, snails, worms and crustaceans. Locally it exploits abundant seasonal resources, such as horseshoe-crab eggs in Delaware Bay. Tundra food also includes insects, particularly important for growing chicks.
The male prepares several ground scrapes and the female selects the final nest site. Both parents incubate. Young soon leave the nest and feed independently; outside breeding birds form flocks and tight resting groups on dry coastal patches.
